Many of my students (teaching in South Korea) don't know how to swim. That is perhaps due to them always having to go to school, study and extracurricular schools so little time is left for leisurely activities. I don't think a lot of the schools have swimming pools, but of that I'm not positive.
As for me, I can swim just fine. I used to be able to do the proper flip underwater-push off the wall when lap swimming. My technique is abysmal compared to what it was when I used to do half mile - mile lap swims, but I don't see how someone would just sink. After all, anyone should be able to doggy paddle and people are naturally buoyant.
